Abstract

The invention provides a long-persistence luminous enameled plate. A glaze used for sintering the long-persistence luminous enameled plate comprises following components in part by mass: 15 to 30 parts of long-persistence luminous powder, 80 to 95 parts of vanadium pentoxide enamel, 5 to 15 parts of tourmaline, 60 to 120 parts of organic additive and 0.2 to 5 parts of dispersant. The long-persistence luminous enameled plate has the main advantages that: (1) because vanadium pentoxide is added into the enamel, the firing temperature is reduced, the high-temperature viscosity is reduced, the enamel serving as a base with low melting point and high transparency can be manufactured, the enamel can be melted at the lower temperature (less than 550 DEG C), the long-persistence time and the luminous brightness of the luminous powder can be greatly kept because the enamel does not produce solid-phase reaction with the long-persistence luminous powder, and the persistence time can reach over 6hours; and (2) the mixed slurry is evenly sprayed on an iron plate by using electrostatic spraying equipment, so the evenness of the mixed coating is greatly improved, the controllable enamel with even thickness can be manufactured, and the glaze of the product has good gloss and has no bubble, sinking and crawling and other defects.

Description

(1) Technical field [0001] The invention relates to a long afterglow luminous enamel plate and a preparation method thereof. (2) Background technology [0002] Enamel is a composite material in which two different materials such as metal material and glass enamel are organically combined under high temperature. It is used in chemical industry, architectural decoration, various road signs, billboards and various report notice boards in offices, interior decoration of vehicles and ships, housings and components of household appliances, and various kitchen supplies, etc. With the rapid development of the economy, the improvement of people's living standards and the enhancement of health awareness, the development of new functional enamel products to further meet and improve people's quality of life has become the main direction of the development of the enamel industry. [0003] Long afterglow luminous enamel is a hot research field in the enamel industry. The material is mai...
